Emergent spatial patterns of excitatory and inhibitory synaptic strengths drive somatotopic representational discontinuities and their plasticity in a computational model of primary sensory cortical area 3b

Frontiers in Computational Neuroscience, 2016
Mechanisms underlying the emergence and plasticity of representational discontinuities in the mammalian primary somatosensory cortical representation of the hand are investigated in a computational model. The model consists of an input lattice organized

Pattern-dependent response modulations in motion-sensitive visual interneurons--a model study. [PDF]

PLoS ONE, 2011
Even if a stimulus pattern moves at a constant velocity across the receptive field of motion-sensitive neurons, such as lobula plate tangential cells (LPTCs) of flies, the response amplitude modulates over time.

Neuronal processing of translational optic flow in the visual system of the shore crab Carcinus maenas [PDF]

, 2011
This paper describes a search for neurones sensitive to optic flow in the visual system of the shore crab Carcinus maenas using a procedure developed from that of Krapp and Hengstenberg.

Spectrotemporal sound preferences of neighboring inferior colliculus neurons: implications for local circuitry and processing

Frontiers in Neural Circuits, 2012
How do local circuits in the inferior colliculus (IC) process and transform spectral and temporal sound information? Using a four-tetrode array we examined the functional properties of the IC and metrics of its micro circuitry by recording neural ...

Nonlinear Hebbian learning as a unifying principle in receptive field formation [PDF]

, 2016
The development of sensory receptive fields has been modeled in the past by a variety of models including normative models such as sparse coding or independent component analysis and bottom-up models such as spike-timing dependent plasticity or the ...

Functional Response Properties of VIP-expressing Inhibitory Neurons in Mouse Visual and Auditory Cortex

Frontiers in Neural Circuits, 2015
Despite accounting for about 20% of all the layer 2/3 inhibitory interneurons, the vasoactive intestinal polypeptide (VIP) expressing neurons remain the least thoroughly studied of the major inhibitory subtypes.

Does Corticothalamic Feedback Control Cortical Velocity Tuning? [PDF]

, 2001
The thalamus is the major gate to the cortex and its contribution to cortical receptive field properties is well established. Cortical feedback to the thalamus is, in turn, the anatomically dominant input to relay cells, yet its influence on thalamic ...

Population receptive field dynamics in human visual cortex.

PLoS ONE, 2012
Seminal work in the early nineties revealed that the visual receptive field of neurons in cat primary visual cortex can change in location and size when artificial scotomas are applied.
